Use of Squarespace Fonts. Can I use them on other platforms.

Hi, I'm just starting my website and the selected template I chose uses ITC Avant Garde Gothic Pro, which is really nice.  Simultaneously I'm on Canva (signed up for Canva Pro) designing my YouTube banner and would like to use the same font. When I google searched it was available on Adobe Fonts (https://fonts.adobe.com/fonts/itc-avant-garde-gothic?mv=affiliate&mv2=red#fonts-section ) however I could only buy it if I signed up for "Creative Cloud" at a ridiculously high price. Any Suggestions?

Obviously I want to have continuity across media, or is that not as important as I think it might be?
